Cancer Test Guide: How Doctors Detect Cancer Early
By Prashant Baghel
Cancer is a complex health condition that happens when abnormal cell growth is uncontrollable in the body. Many types of cancer develop silently without showing any signs in the body. That’s why early diagnosis plays a crucial role in successful treatment and long-term survival rates. When cancer gets identified early, doctors can often treat it more effectively, with fewer complications and a better quality of life for patients.
In this article, we’ll discover more about how cancer is detected and the tests used, and why early diagnosis matters in cancer care.
Why early detection matters
Early diagnosis in healthcare, especially in cancer treatments, can make a huge difference. Early-stage cancers are usually easier to treat and manage. Additionally, early-stage cancers respond better to cancer treatments.
Benefits of early detection include:
- More treatment options, including less invasive surgical procedures
- Reduced treatment duration and side effects
- Lower overall treatment costs
- Improved physical and emotional well-being
Common warning sign that may lead to cancer testing
Although cancer screening can detect cancer before symptoms arise, certain warning signs might lead the doctors to recommend some cancer testing and methods.
These include:
- Unexplained weight loss or ongoing fatigue
- Consistent pain, swelling, and sores that don’t heal
- Changes in bowel movements
- Unusual bleeding
- Vaginal discharge
- A lump or thickening of any part of the body
- Chronic cough
- Hoarseness
- Difficulty swallowing
All of these symptoms do not always indicate cancer in any person, but medical evaluation is considered essential to rule it out or catch it early without any delay.
Types of cancer tests used for early cancer diagnosis
Here are some of the cancer screening tests used for early diagnosis in suspected patients, including:
Cancer screening tests
These screening tests are often performed in people with any real symptoms of cancer but might be at a risk of age, gender or family history of cancer. Performing these cancer screening tests helps to identify cancer at its earliest, which is considered the most treatable and manageable stage.
Common cancer screening tests may include:
- Mammograms for breast cancer
- Pap smear and HPV testing for colorectal cancer
- Colonoscopy and stool tests for colorectal cancer
- Low dose CT scan lung cancer in suspected patients.
- PSA testing for prostate cancer
Many healthcare providers recommend screenings based on guidelines and risk factors.
Blood tests and laboratory tests
Blood tests play a crucial role in cancer diagnosis; while they usually cannot confirm the cancer on their own, they can reveal abnormal patterns that require further medical intervention.
Common blood tests may include:
- Complete blood count (CBC) to detect blood-related cancer
- Tumor marker tests, which measures substances often produced by cancer cells
- Liver and Kidney function tests to assess organ health
Performing blood tests is also useful for monitoring cancer and its treatment response, as well as detecting the chance of recurrence in patients.
Imaging tests
Performing imaging tests allows doctors to look inside the patient’s body and detect any abnormal growths or lumps. These imaging tests help to locate many types of tumors, measure their size, and determine whether the cancer has spread or not.
Common imaging tests may include:
- X-rays
- Ultrasound scans
- CT Scans
- MRI scans
- PET scans
Performing these types of imaging tests plays an essential role in both early detection and cancer staging.
Biopsy
A biopsy is the most common way to diagnose cancer. During this procedure, the doctor might remove a small sample of tissues or cells from the suspicious area.
The sample is often performed by a pathologist to determine:
- Whether cancer cells are present or not
- The type of cancer
- How aggressive the cancer type is
Biopsies can be performed by using needles, depending on the type of cancer, along with endoscopy or surgery, depending on the type of tumor’s location.
Genetic and molecular tests
Some types of cancers are often linked to inherited genetic mutations. Performing Genetic testing helps to identify people with higher risk of developing certain cancers.
Molecular testing analyse cancer cells at a genetic level to:
- These tests help to predict how aggressive the types of cancer are.
- These tests help to guide targeted therapy and precision medicine.
- Performing these tests helps the doctors to choose the most effective cancer treatment.
These genetic and molecular tests are considered valuable for patients with a strong family history of cancer.
Who should consider cancer testing?
Cancer does not affect anyone in the same way; some individuals might have a higher risk due to increasing age, genetics, lifestyle choices, or environmental exposure. Understanding these risk factors in their early stages allows many doctors to recommend all kinds of tests. It helps to diagnose at an earlier and more treatable stage.
Doctors might recommend cancer testing if you have certain conditions, including:
- Patients with a family history of cancer
- People are above the age a certain stage
- Smoking cigarettes, excessive alcohol consumption
- People with lifestyle- related conditions
- Having long term exposure to harmful chemicals
- Experiencing long term symptoms
Performing regular checkups and cancer screening tests helps to identify risk factors early and ensure timely cancer screening tests.
How do doctors choose cancer tests to perform on suspected patients?
Doctors decide which cancer tests to use through a careful, step-by-step approach aimed at ensuring an accurate cancer diagnosis while avoiding any types of unnecessary treatment procedures.
- Many healthcare providers would begin with understanding the medical history and lifestyle habits of the suspected patients.
- Family history of cancer
- Conducting physical examination and its findings
- Analysing any current symptoms, if any
Based on the above information, many doctors recommend the most appropriate diagnostic tests.
